<dd>
<p>Optional. An object with some or all of the following properties:</p>
<dl>
<dt><code>localeMatcher</code></dt>
<dd>The locale matching algorithm to use. Possible values are <code>"lookup"</code> and <code>"best fit"</code>; the default is <code>"best fit"</code>. For information about this option, see the <a href="/en-US/docs/Web/JavaScript/Reference/Global_Objects/Intl#Locale_negotiation" title="The Intl object is the namespace for the ECMAScript Internationalization API, which provides language sensitive string comparison, number formatting, and date and time formatting.

<dt><code>timeZone</code></dt>
<dd>The time zone to use. The only value implementations must recognize is <code>"UTC"</code>; the default is the runtime's default time zone.

<dd>Whether to use 12-hour time (as opposed to 24-hour time). Possible values are <code>true</code> and <code>false</code>; the default is locale dependent. This option overrides the <code>hc</code> language tag and/or the <code>hourCycle</code> option in case both are present.</dd>
<dt><code>hourCycle</code></dt>
<dd>The hour cycle to use. Possible values are <code>"h11"</code>, <code>"h12"</code>, <code>"h23"</code>, or <code>"h24"</code>.

</dl>
<p>The following properties describe the date-time components to use in formatted output, and their desired representations. Implementations are required to support at least the following subsets:</p>
<ul>
<li><code>weekday</code>, <code>year</code>, <code>month</code>, <code>day</code>, <code>hour</code>, <code>minute</code>, <code>second</code></li>
<li><code>weekday</code>, <code>year</code>, <code>month</code>, <code>day</code></li>

<li><code>hour</code>, <code>minute</code>, <code>second</code></li>
<li><code>hour</code>, <code>minute</code></li>

<p>Implementations may support other subsets, and requests will be negotiated against all available subset-representation combinations to find the best match. Two algorithms are available for this negotiation and selected by the <code>formatMatcher</code> property: A <a class="external" href="http://www.ecma-international.org/ecma-402/1.0/#BasicFormatMatcher" rel="noopener">fully specified <code>"basic"</code> algorithm</a> and an implementation-dependent <code>"best fit"</code> algorithm.</p>
